TARIFF EQUIVALENT AND FORGONE TRADE EFFECTS
OF PROHIBITIVE TECHNICAL BARRIERS TO TRADE
CHENGYAN YUE AND JOHN C. BEGHIN
We derive a method to econometrically estimate the tariff equivalent and forgone trade effects of a
prohibitive technical barrier to trade (TBT) based on Wales and Woodland’s Kuhn–Tuckerapproach to
corner solutions in consumer choice. The method es the lack of observed data on bilateral trade
flows and accounts for differentiated goods by place of origin. We apply the derived random utility
model to international trade in apples to identify the tariff equivalent of prohibitive phytosanitary
barriers imposed by Australia on potential imports of New Zealand apples. We estimate the forgone
apple trade between the two countries, the implied trade injury imposed by Australia on New Zealand,
and the welfare loss to Australia. The removal of the Australian policy would welfare gains
around US$50 million annually for Australia.
Key words: corner solution, Kuhn–Tucker model, New Zealand apples, phytosanitary, prohibitive
barrier, technical barrier to trade.
